1. WHAT DOXADURA IS AND WHAT IT IS USED FOR
Doxazosin is one of a group of medicines called alpha-blockers.
DOXADURA tablets are used to treat high blood pressure (hypertension) or the symptoms
caused by enlargement of the prostate gland in men.
In patients taking DOXADURA to treat high blood pressure (hypertension) DOXADURA works
by relaxing blood vessels so that blood passes through them more easily. This helps to lower
blood pressure.
In patients with enlargement of the prostate gland, DOXADURA is taken to treat frequent and/or
poor passing of urine. This is common in patients with enlargement of the prostate gland.

DOXADURA works by relaxing muscle around the bladder exit and prostate gland so urine is
passed more easily.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE DOXADURA
Do not take DOXADURA if you:
• are allergic to doxazosin, other types of quinazolines (such as prazosin or terazosin) or any of
the other ingredients of DOXADURA tablets listed in section 6. This may have been itching,
reddening of the skin or difficulty in breathing.
• are breastfeeding
• have an enlarged prostate gland (benign prostatic hyperplasia) and have low blood pressure
• have a history of a condition known as ‘orthostatic hypotension’ which is a form of low blood
pressure that causes you to feel dizzy or light-headed when you stand up from sitting or lying
down
• have an enlarged prostate gland with one of the following: any kind of congestion or blockage
in your urinary tract, a longstanding infection of the urinary tract or you have bladder stones
• have overflow incontinence (you do not feel the urge to urinate), or anuria (your body is not
producing any urine) with or without kidney problems
Warnings and precautions:
Talk to your doctor or pharmacist before taking DOXADURA:
• If you have liver disease
• If you are pregnant or trying to become pregnant
• If you are also taking other medicines
• If you have heart disease
Children and adolescents
Do not give this medicine to children under 18 years of age since the safety and efficacy of
DOXAZOSIN in this age group have not been established.
If you are undergoing eye surgery because of cataract (cloudiness of the lens) please inform your
eye specialist before the operation that you are using or have previously used DOXADURA. This
is because DOXADURA may cause complications during the surgery which can be managed if
your specialist is prepared in advance.

Before starting treatment with DOXADURA your doctor may perform tests to rule out other conditions
such as prostate cancer that may cause the same symptoms as benign prostatic hyperplasia (enlargement of
the prostate gland).
Persistent painful erections may occur very rarely. If this happens you should contact a doctor
immediately.

When you start to take DOXADURA you may experience faintness or dizziness caused by low
blood pressure, when getting up from sitting or lying down. If you feel faint or dizzy, you should
sit or lie down until you feel better and avoid situations where you might fall or hurt yourself.

Your doctor may want to measure your blood pressure regularly at the start of therapy to reduce
the possibility of these effects happening.

Other medicines and DOXADURA:
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
There are some medicines that may interact with DOXADURA

Some patients who take alpha-blocker therapy for the treatment of high blood pressure or prostate
enlargement may experience dizziness or light headedness, which may be caused by low blood
pressure upon sitting or standing up quickly. Certain patients have experienced these symptoms
when taking drugs for erectile dysfunction (impotence) with alpha-blockers. In order to reduce
the likelihood that these symptoms occur, you should be on a regular daily dose of your alphablocker before you start drugs for erectile dysfunction.
DOXADURA may lower your blood pressure even more if you are already taking other
medicines to treat high blood pressure.

DOXADURA with food and drink
Please refer to section 3.

your doctor or pharmacist if you are unsure.
DOXADURA is usually taken once daily. DOXADURA may be taken in the morning or the
evening.

increased (within 1-2 weeks interval) to the recommended dose (2mg or 4mg daily).
In some circumstances the dose may be increased to a maximum of 8mg daily if you are being
treated for prostate enlargement, or to a maximum of 16mg if you are being treated for high
blood pressure.

You have been given a calendar pack that will help you remember to take your tablets. If you are
taking more than one tablet a day, you must ignore the marking for the day, printed on the back
of the blister.
Because high blood pressure is treated in order to prevent problems from arising, you may have
no symptoms at all while taking DOXADURA. Even if this is so and you feel well, you should
not stop taking your blood pressure medication unless instructed to by your doctor.
Don't change the dose or stop taking the tablets without first checking with your doctor.
